Oddball F450 ex DND for sale on Crown Assets

[Grant Bowker]

Both by appearance and the maker's labels it was built as an ambulance. Appears to have originally been painted flat green with a later repaint in a glossier, darker tone.
Probably at its best on hard surfaces or gravel roads, possible firm earth. Most ambulances are quite heavy, so not at their best in soft fields although the 4x4 might help (get further into trouble before needing to be towed out).
It's being sold out of Downsview - central Toronto. Other items from CFB Trenton or Borden often seem to be sold from the bases, not brought in to Toronto. Is there a reserve Field Ambulance unit in Toronto that might be the source?
